Looking back in time: Geological perspectives on Canadian Rockies

If you are in the Canadian Rockies, you must be wondering, why are the colors of these lakes so blue? Why are some of the cliffs so sharp and some are blunted? What is the difference between a Glacier and an Icefield?

Formation of the mountains

  • 500 million years ago, this area was by the ocean and by the equator. This is where Pacific oceanic plate and American continental plates met. Heavier oceanic plate colliding with lighter continental plate created something like a ‘big bang’ 500 million years ago, causing sedimentary rock to rise up like a ‘fold’. If you look closely towards the bare cliffs around you, you can see clearly visible layers. The extreme pressure of the tectonic shift caused the whole sea bed, which had layers and layers of sediments over the ages, to rise up. The top most layer is the most recent, albeit millions of years old.
  • Since it was the tropics back then, an abundance of sea life and fossils can be found in the layers of sedimentary rock here. Different layers have different colors and texture from different types of rock like brittle shale, softer limestone or sandstone. Some contained hydrocarbons due to vegetation (forming into coal) and animals (forming into petroleum).
  • What is currently British Columbia, was formed during this tectonic collision from magma. But the Rockies were created from sedimentary layers pushed up; that is why you will not find any igneous rocks, like granite, here.
  • If you look carefully, the sedimentary layers are not parallel which it was when it was formed. The layers also seem to have broken along a vertical line. Due to high pressure from the weight of the rocks above, a fault develops which is essentially a crack. The rocks on either side of the faultline, slide up or down, thereby creating a phase shift. Other types of faults, caused by tectonic movements and glacier forces are also visible throughout the Rockies creating shapes.
  • Another factor to consider is the weathering by wind and glacier movement for millions of years, causing some cliffs to be extremely steep and some peaks somewhat blunted.

Color of the Lakes

Heavy and thick glaciers formed most of the lakes in this area. As gravity pulls the glaciers, the incredibly heavy ice grinds the rock into rock flour. It is so fine and light, it takes long time to settle down at the bottom of the lake. Bright sunshine is absorbed by the rock flour and only blue light from the spectrum is reflected. That’s why the color of the lakes are such vibrant blue, especially when the sun shines the brightest.DSC_1812

Glacier vs. Icefield

Best analogy to understand this is to think of the Icefields as a lake and glaciers being the rivers coming out of the lakes. Most glaciers are formed from the icefields, and follows gravity. Movement of glaciers is much slower compared to a river, comparable to growth rate of your fingernails. There are a number of glaciers in the Canadian Rockies, with the Athabasca glacier and Saskatchewan glaciers being the largest and most significant. Most lakes and rivers in this area are fed by one of these glaciers, thereby creating some of the purest form of water. Columbia Icefield is one of the largest ones in the world. It is a staggering 200 square kilometers wide and at areas more than 200 meters deep. You can spot flanks of the icefield on top of peaks and plateaus from the entire stretch of the Icefield Parkway.

Arenal Volcano

Back to Costa Rica Itinerary

As one of the youngest stratovolcanoes in the country and the world, Arenal has been erupting continually since 1968. The lava and pyroclastic activity has been a hazard to the local community ever since, yet the conical shape of the majestic volcano attracts thousands of tourists every year. Due to the constant volcanic activity, there are thermal springs abundant in the area as well giving another reason for tourism to flourish.

Geology

The arc of the Costa Rican volcanoes, namely Poas, Irazu, Arenal, Miravalies is located just above the subduction zone created by the Cocos plate moving under the Caribbean plate. It is also considered a part of the Pacific Ring of Fire. The Arenal volcano is estimated to be still in the process of building up on its 1600m cone. With eruptions dated back to almost 7000 years ago, the latest cataclysmic eruptions were in 1968 causing a lot of damage to human lives and property. The lava flows and pyroclastic activity afterwards has been confined to the flanks and valley nearby. A walk around the park and a close examination of the rocks and soil show evidence of basaltic andesite lava flows. Also around the base of the volcano, in a ring shaped arc, there are hot springs that attract a ton of tourists.

Around the Volcan Arenal

Built as a national park now, it is assumed safe to hike around the volcano, although we heard from local guides that a hike to the crater might not be advisable because of a chance of sporadic gaseous explosions. Landslides in the lower flanks might also cause a hazard sometimes.

The perfectly shaped cone can be visible from anywhere near the volcano, though the haze and cloud cover often covers the summit for an extended period of time. It is illegal and difficult to hike to the crater of Arenal, but you can do so in the nearby extinct Cerro Chato.

There are two trails emanating from the park entrance in Arenal – one less than a mile long to a lookout point and another less than 2 miles to the south to see the latest lava flows. Both trails take you through forested and hilly climbs towards the volcano. You are sure to get a good look at the basaltic lava flows and remnants of igneous rocks. The shorter trail is an easier hike and has steps to go up through lava rocks to reach the base of the volcano. In the early mornings before the clouds start forming, there is a good chance that you might see the crater for a little bit, but in the afternoons the probability reduces significantly. On the way back you should be able to easily walk back through dense forest. There won’t be a ton of wildlife here, so no need to hire a guide if you are aware of the science to take advantage of the plentiful evidence of volcanic activity here.

Tip – You are still in the flanks of a rainforest, so bring ponchos/umbrellas and a bottle of water, and obviously sturdy shoes for the walk through loose and newly formed rocky trails.

Poas Volcano

Back to Costa Rica Itinerary

The hike to the viewpoint for the principal crater was easy, but the wait for the cloud cover to disappear was not. It was an early January morning and it was windy and misty. From a distance, the Poas mountain top was covered by dense fog. We tried the same visit two weeks back on the first day in Costa Rica, but there was a dense cloud cover too. Even after waiting for 2 hours, we could not see anything.
But today the differentiator was the chilly wind gust. After only a 10 minute wait the majestic crater with the dreamy sulphur fumes showed up. It was a show indeed to see the cloud curtain getting lifted slowly and the intricate details of the panorama unveiling at an leisurely pace. But the clear skies did not last long, and once the principal crater was covered in dense cloud again, we hiked 10-15 minutes to the secondary crater which is now a lagoon.

The last eruption in the principal crater was in the 1950s but that in the secondary crater was way back. Therefore we don’t see any fuming gas in the secondary one. Nevertheless it was a sight not to be missed too. It is definitely worth the hike to the lagoon.

There’s also another trail that goes around the lagoon that does not have much view of the craters but has some wildlife and a lot of plants to spot. It took us about an hour but we took time to take photos, and explore the trail. That trail starts from the viewpoint of the secondary crater and ends near the parking lot.

Tip 1: In a day trip from San Jose, combo tours of Poas, Doka Coffee estate and Sarchi village is really convenient. But for visiting Poas only, try booking a ‘only Poas hike’ tour from San Jose area. Should cost no more than $60 pp. Taxi ride one way is about $60, and uber costs a tad less. Park entrance is $15 pp in high season ($10 in low). Also, for the savvy traveler, there’s a public bus from Alajuela autobusera around 8:30am, and returns from Poas at 2:30pm. Costs ~$2 one way. You can find the details of the bus schedule at visitcostarica.com.

Tip 2: do not go by weather forecasts. There are a few microclimates that change by the minute. On a day when the valley may be dry and bright with sunshine, the mountain top can be densely packed with clouds and rain. Try going there on a day of your choice and stay up there for a while hoping for the cloud cover to go away.

Tip 3: keep your camera ready and eyes wide open once you’re up there. The window of opportunity to view this majestic crater could be extremely short lived.

Monument Valley, AZ

Back to The Grand Circle Canyon Trip

With all the bags packed, gas tank full, and gutted with a pile of energy, we reached the entrance of the fantastic Monument Valley National Park through the south approach of the Rt 163.
The person at the ticket counter did have a weird, unimpressed look on his face when he glanced at the car we were in, a sedan. We were taking a chance, albeit there were a scarce number of sedans, to complete the 17 mile scenic drive. The drive itself, at least for the first part, was not challenging for the car, and we stopped at numerous vista points, hiked a little, and of course took photos from variety of angles at variety of shooting modes. 🙂 It is imperative that you carry a printed copy of the map, due to obvious reasons!

monument-valley
The most noteworthy were the Elephant Butte, the Three Sisters, the Camel Butte, the Rain God Mesa, the Totem Pole, the Yei Bi Chei, Artist’s Point, and the Spearhead Mesa. Thanks to the valiant attempts by the Geologist wife at making the naive husband understand the structural details and formation histories of the Mesas, Buttes, and spiral structures, the visual images are still crystal clear. To the untrained eye, standing in the middle of the valley would make you feel like you’ve landed on the red moon. The steep sides of the Mesas and Buttes, which are at abundance in the area, would take your breath away, when you’d realize that those formations are made just by hundreds of years of erosion by air and water only! The different shapes on display in the valley are seen from different vantage points along the 17 mile bumpy, steep, and rutted  ride. The red color of the soil, and the formations is ferric oxide, resulted from the heavy weathering of the plateau that is rich in iron. From the ancestral Rocky Mountains, to the current day Monument valley underwent several geologic events including uplifts, cracking, and constant erosion. But as with all geological formations, the earth continues to alter the face of the area.
Warning: Please keep an eye on the fuel levels, and the engine temperature gauge, as there are not many gas stations in the area and temperatures can steeply rise. Also, unless driving a four-wheeler, DO NOT try to go off-road (while the prospective view would be alluring, there could be serious trouble for two wheel drive cars).

Well, we could spend a full day here given a chance, but we had some ground to cover before dusk, therefore we set out for the next destination, Kanab, UT. But wait, there was more! There is only one road, highway 163, that goes through the park up north. When we were heading north, after a mile or so on a
road, straight like an arrow, we suddenly noticed something that we must have hated ourselves if we did not; the famous, much photographed approach road to Monument Valley. That was exactly where Forrest Gump finished his run too! Yes, we had to stop another hundred times and drive aimlessly to find the best vantage point. But it was well worth the time. A treat to the eyes, that my literary prowess would not be able to do justice with.

 

The Canyons – Grand Circle Trip

In a journey to unknowns, through barely traveled roads, with only a dream in mind, and the best friend for company, we set out to look at mother Earth at its best – the spectacular canyons of the American south-west. In this journey through historic crossroads and beautiful formations, we drove more than 3,500 miles for 8 days with Tom Petty and Pink Floyd-on repeat.

fa5bf-summary

Montage of our cross-country travels

In the drive through 9 states, hikes up the mesas, drive in river gorges, unpaved country roads, we met some amazing people, tasted aboriginal cuisine and pinned memories for a lifetime. We started this 3,500 mile trip from Austin, TX and ended in Indiana crossing TX, NM, AZ, UT, CO, KS, MO, IL, and IN.

The Canyons and POIs covered – Albuquerque, NM, Monument Valley, Zion National Park, Bryce Canyon, Capitol Reef, Arches National Park, Canyonlands National Park.

Itinerary and Travelogue

Day 1 | Austin, TX to Clovis, NM | 500 Miles

We loaded up the trunk of the sedan, and bid adieu to Austin which was my home for the summer, 2012. Apprehensive about how the car would endure the 3500 mile long drive, we set out for the greatest adventure of our lives so far. Loaded with caffeine, we charged for about 500 miles on the first day, taking advantage of the close-to-zero traffic and great weather. In an apparently uneventful day, we managed to enter New Mexico, and stopped for a night in a small motel in the little town of Clovis, NM. Had Mexican food for dinner, and called it a day pretty early.

Day 2 | Clovis, NM – Albuquerque, NM – Aztec Ruins – Farmington, NM | 540 Miles

On the Saturday morning, loaded with continental breakfast, and coffee (well, could not spot a Starbucks around), the drive to Albuquerque, NM began. We reached the town around noon, and found a nice place for lunch on the historic Route 66. We knew that the

29059-kimotheater

KiMo Theater (Albuquerque)

Route 66 would be with us for a major period of the drive, but this was probably the only spot en route, that had any touristy value. Route 66 was laid in 1926, and ran from Chicago, IL to Santa Monica, CA through MO, KS, OK, TX, NM, and AZ, a 2300 mile long endeavor. The city of Albuquerque, NM, though a historic city, did not have a vibe about it. Rusty buildings, and lower than expected pedestrians on the main street was disappointing. Apart from the historic (and often referred to as ghostly) KiMo Theater, the downtown did not have much to offer.

So, we decided to focus on the later part of the day, which was to check out other national parks along the way. We did some research on the go, and decided to swing by the Aztec ruins in Aztec, NM. We reached towards the end of the day’s hours, but managed to take a close look at the ruins in the park. There was a self-guided tour available, and all you had to do was to walk along the designated trail. Intriguing aspects of Aztecs’ lives were

a9afe-219427_4511021212033_2067413213_o

Aztec Ruins, NM

depicted in the rooms that were built thousands of years ago. Skillful stone masonry, wood roofing, and other architectural structures apart, the great Kiva, the subterranean structure that housed major events in Aztecs’ lives, were literally enlightening. Further details about the Aztec Ruins National Park can be found here. It is a must visit for anyone interested in the history of the native civilizations of the area.
At the end of a busy traveling day, we decided to stop at the nearest small-town of Farmington, NM. An early start of the next day was looming!

Day 3 | Farmington, NM – Four Corners – Monument Valley – Kanab, UT | 300 Miles

Poetic literature often associates beauty with greenery, ice-capped mountains, or serene water bodies. But our rendezvous with some of the most barren lands in the area rendered those definitions of natural beauty, incomplete. On our way to the Monument Valley, UT, from the Travelodge in Farmington, we encountered numerous Mesas and Buttes in the Colorado plateau. With elevation slowly increasing, the human habitations were becoming scarce with every mile traveled.
As we entered the Navajo habitats, we came close to a distinct point of interest: The four corners monument. A part of the Navajo Nation parks, the area is very remote, but once you get there, it is a serene environment with nothing other than square miles of open barren land surrounding it. It is the only place in the USA where four states Utah, New Mexico, Arizona, and Colorado meet. Spend a few minutes with the local Navajo artisans to check out their handmade jewelry, crafts, and traditional food. Nothing extravagant on display, but if you must, it is better to buy from these places compared to larger visitor parks so that the money goes to their families.

The next 100 odd miles approaching Monument valley from south, through highway 163 was like a John Denver song playing in repeat mode; Mesas, serene valleys, and country roads. Remember the scene from Forrest Gump where he runs across the country through these very roads with Monument Valley in the background? The entire stretch of highway monument-valley163 approaching or leaving the park, it is a vista you’d fail to erase from memories. After multiple stops to capture the panorama, we entered theMonument Valley national park, also a part of the Navajo nation parks and recreation areas. Further details about Monument Valley can be found here.

Our aim was to put icing on the cake by setting foot in the charismatic Antelope Canyon in AZ by the end of the day. But alas, not everything may go as planned, since the weather Gods intervened with a heavy downpour that flooded the canyon bed. We were disappointed to reach the canyon through Page, AZ, yet it was something that we did not mind paying another visit, another time.

Rather than wasting precious time, we headed for the Horseshoe Bend. It is conveniently located on Rt 89 (although I hear that a landslide in early 2013 closed that approach road). An extremely tiring hike taking close to 90 minutes, one-way, was unplanned, but

Trip Details - Grand Circle Canyons

Horseshoe Bend (Page, AZ)

rewarding. The sand on the hike path may seem like a nuisance, but it is a walk through history. From pre-historic times, the biggest sand dune in the region went through a lot of weathering, resulting in sand stone layers known as ‘ergs‘. As seen in the photo here, it is a fantastic view to witness a vertical drop of a whooping 980 meters, and a 270 degree turn by the Colorado river. You need a wide angle lens to capture the entire canyon bend in the picture. The iOS panorama mode does the job too! But the mighty Colorado river has eroded through the sandstone from millions of years to get to this natural bend, and may be in the near future (in geologic time scale), we might witness a natural bridge where the river abandons the circular bend altogether.

Anyway, after a thousand pictures and dipping in the serenity of the spectacular Horseshoe Bend, our tired, dehydrated souls sought the comfort of a bed and warmth of dripping hot water from the shower. So we started driving, again, to search for our hotel in Kanab, UT, Shilo Inn and Suites, a less than standard hotel in the small Mormon town. In spite of being a relatively famous town for the shots in a number of Hollywood movies, the town remains closed for businesses on Sundays(!). We managed to not find a decent place for dinner, and found it hard to locate even a gas station that was open on Sunday. Who knew?

Day 4 | Kanab, UT – Zion National Park – Bryce Canyon – Moab, UT | 300 Miles

Monday morning threw no jitters as we left the town right at dawn to hit the curves and tunnels en route to Zion National Park. We had half a day, so went straight at it after

whizzing past the entrance using our NPS card. Through the visitor center, we walked and hiked through the mesmerizing landscapes of this huge national park. We walked through rivers with ankle high water, hiked to top of the canyons, drenched in emerald pools and sipped the beauty of the flora and fauna around barren yet beautiful landscape. Our favorite POIs were the lower and upper falls, emerald pools, checkerboard mesa, the narrows, and the main canyon. Honestly, one can spend 2-3 days easily and hiking every day all day, yet to cover all the spots. Half a day was crazily below average time people spend here. Nevertheless, we will cover the geology and the environmental tales of Zion in a separate post.

For now lets focus on the next spot – Bryce Canyons. We had a little bit of lunch and headed to Bryce Canyons National Park, a mere 50 minutes drive. But boy, what a drive it was. Surrounded by a landscape that drastically changed every 15 minutes. We went from green river valley to rocky cliffs to barren country side in a matter of minutes. Until we crossed the famous natural ‘bridge’, we had a feeling we are lost and going in the wrong direction. After entering the park, it seemed to be a different world, at least compared to Zion where we were just less than an hour ago.

bryce2

Vivid colors of the Hoodoo’s

From the visitor center to all the POIs, it seemed extremely touristy and the paths are all paved. Not many wilderness trails exist probably for obvious reasons – that the landscape is dangerous with steep cliffs and nothing to hold on to, and sharp drops to the bottom of the canyons. The highlight of this park has to be the ‘hoodoos’ which are best viewed at sunset. The red and orange hues come out swinging at the dying lights of the day. The gorgeous structures are actually formed by wind corrosion and not water weathering. The Bryce Canyon is not really a canyon, but a inverse dome where the bottom layer of rock is weaker than the top layer. Therefore with time, the bottom layer gets corroded faster than the top layer, and creates these fanciful ‘hoodoos’.

There is a steep and slippery pathway to go to the floor of the ‘canyon’ or dome to be with the hoodoos. It is a tough climb back but definitely a must since at various levels, the photo-ops and the panorama changes vividly. Even though it has a lot to offer, one day here should be enough for a savvy hiker to complete.

After a tiring day, we headed towards Torrey, UT which is close to our next stop – Capitol Reef National Park.

Day 5 | Torrey, UT – Capitol Reef – Arches National Park – Moab, UT | 150 Miles

Not a single park in our agenda deserves a half day, but still we pushed on for two more natural wonders. First on the list – Capitol Reef National Park. Possibly the largest of all the parks we covered in this trip, the name of the park comes from the famous whitish domes that resemble the US Capitol building. The primary attraction here is the Waterpocket fold which is a faultline in geologic terms representing a collision of two plates 70-80 million years ago. The structures that we see and feel awestruck were formed due to million years’ of weathering. Viewing the faultline from the scenic overlook is a fascinating experience.

Another interesting experience while in this park was to drive into a river gorge, infamous

capitol-reef-gorge2

River gorge, Capitol Reef

for flash floods upon sudden downpours. While it requires a 4×4, we went in with a sedan and parked at a safe distance before venturing on foot to the gorge. As seen in the picture here, I used Rupsa as a scale to show the enormity of the gorge. Imagine a river flowing through this slot canyon! Humbling indeed that we appear so small when compared to the wonders of nature.

Talking about humans, we found traces of petryglyphs (symbols and letters imprinted on

capitol-reef-petryglyphs

Petroglyphs at Capitol Reef

rocks), in various parts of the park signifying the presence of ancient aztecs and their villages. There are a number of hiking trails that take you to the arches, canyons and overlook trails for impressive photo ops and bit of exercise.

After about 5-6 hours in the park, we headed out to Arches National Park near Moab, UT. Just about 100 miles away, it awaited another surprise for us. A park full of arch like structures with the center eroded making it see through! Natural wonders are like McDonalds in this area, only that the flavors and taste differ so significantly. We drove through the park first just to scale the area and to prioritize our hikes. This is a popular park and a lot of visitors actually stay overnight camping. We heard that the starry nights are fascinating because of the lack of air and light pollution.

There are tens and thousands of arches of various kinds here. The popular and our favorite ones are – delicate arch, double arch, window/ventana arch, and turret arch. The geology behind the formation of the arches is intriguing. Million years ago, this land was under the sea indicated by the discovery of fossils of oceanic creatures, mollusks, shells. Once the seas receded, the large basin covered with thick salt beds was covered in turn with large rocks carried in by the streams and rivers. The salt levels being lighter, pushes up the rock layer to create higher rock formations from the valleys. After groundwater dissolved the salt layer, the top layer collapsed into wall like structures. After 100-150 million years’ of weathering, these tall wall like structures took shape of these arches which are made of soft red sandstone. These arches are not permanent structures; new arches are being formed every day while old ones collapse.

The hike to the Delicate arch is a strenuous one, but extremely rewarding. The other arches have their own charm with various structural intricacies, and variation of grandeur. One can easily spend a week here just soaking in the charm of the delicate natural wonders.

Day 6 | Moab, UT – Canyonlands National Park – Denver, CO | 150 Miles

Running from one national park to the other would tire you out right? Nope. If you are in good physical shape, the sheer variety of the natural wonders and their splendor would be able to keep you going. An overnight stay in the quaint town of Moab, UT, we ventured out to the last one in our list – Canyonlands National Park.

This one is a humongous park with three different sections – Island in the sky, The Maze and The Needles. The Maze and Needles are not accessible from the Island in the sky. Our POI was Island in the Sky and the primary spots – Green River Outlook, Upheaval Dome and Grand View. From the Green River outlook, we could see the entire river valley with the canyons and the bends of the river.

Geologically, the two mighty rivers – Green River and Colorado River flowing together in the park has created the three segments and the entire landscape of this area. There are not many paved roads for normal cars but if you have a 4×4, lot of off-roads are available to explore the canyon and the river banks.

After spending about 5-6 hours in the park, we headed out to the mid-west, Denver being the first stop.

A shame that we had to cover all these splendid parks in only a week, but to our credit we stayed fit and finished strong. We are going to hit these parks again for slightly longer time at a later time. Hope to update this travelogue with a lot more scientific and picturesque logs at that time.

 

Haleakala National Park

Back to Maui

Back to Hawaii

Driving on the misty and foggy winding road, cherishing the melody of a country song, the ascend through the Advection fog levels is surely one of the most fascinating journeys we had in Hawaii. A mere 2 hour drive from the sea level to the top of the crater, the Haleakala National Park is an attraction where tourists can either spend an entire day, or spend specific parts of the day for various reasons.

Geological History

Haleakala is a massive ‘Shield’ volcano taking up more than 75% of the area of Maui.It is formed by lava flows from the ocean floor that started merely 2 million years ago.The lava flow is believed to have originated from the hotspot (that sits below the Big Island now due to the movement of the oceanic plate), and the oldest exposed lava in this area is dated to about a million years old.

At the top of the park, there is a massive depression/crater which is ~7 miles in diameter and 2500 feet deep. The crater itself sits at at a height of ~10,000 feet. Weird as it may seem, but the crater itself was not of a volcanic origin. Instead, the original summit of the volcano collapsed due to weathering and created the depression, scientifically named as a ‘caldera’.

Contrary to popular belief, scientists argue that the volcano is not extinct yet and is merely dormant. There have been several eruptions from various parts of the volcano, especially the eastern region, in the last 100,000 years, with the last eruption dating back to 1700’s. The trailing edge of the hotspot might still be lurking under the eastern ridge of the island. If possible, a journey through the eastern edge of the park would surely give you a glimpse of the latest eruptions. The road is not paved and may not be possible to venture out with a rental car. Check out the official take on the potential for Haleakala rising from the ashes.

Exploring the Park

Once past the park entrance, the winding road takes you straight to the observatory level from where there are trails leading to the famous Haleakala Crater. From the top, looking eastward on a clear day, enjoy fascinating views of the Mauna Kea volcano (in Big Island)

with the advection zone cloud and Southeastern Maui landscape in foreground. Because of the altitude and stillness in the air, and being so far from

haleakala-2

Spot Mauna Kea to the right

the city lights, Haleakala is an amazing spot for stargazing. If you are prepared to withstand the cold and the wind, arrive an hour before sunrise or stay on for a couple of hours after sunset to have one of the clearest views of the Milkyway, tens of constellations, and stars.

Tourists often choose to drive up before sunrise or return after sunset. Although the drive could be hazardous (especially for travelers with a major jetlag), on a clear enough day, the panorama and the experience of a sunrise or a sunset is spectacular. Just be warned that the environment is extremely unpredictable and the day of your choice could very well be the one where the Gods decided to drop a load of cloud on the advection zone making it impossible to spot the Sun near the horizon. But most of the times the cloud clears out with the trade winds blaring in.

While you are at the top, take one of the trails (Halemau’u or Sliding Sands) to step foot on the caldera. Look around to spot volcanic activities and lava trails. Walk on the red soil

haleakala-glory

“Glory” at the top of Haleakala

devoid of any vegetation. Photos of the landscape with smaller hills and the barren land with boulders and rocks can trick an unsuspecting eye on believing its on the moon. Thepaved road and the clouds do give it away though. Keep an eye out for some rare phenomenons like a ‘Glory’.

 

 

Things to Know

  • Park entrance costs: $5 per person or $10 per vehicle, valid for 7 days. Keep the receipt in the car since you can use it in your stop at Kipahulu in Hana Highway as well.
  • Driving: Be extremely careful on your descend from the top as there are not many railings or shoulders in the curves, and the road is extremely narrow. Driving in the dark can be perilous if extra caution is not taken. Shift to lower gear (yes even in an automatic shifter), and drive below speed limits. Tailgating cars can wait. If you are going for the sunrise, or returning after sunset, the cloud/fog starts forming at different levels and can be extremely dense. From our experience, having a GPS actually helps in preparing for the next turn/bend as well.

Road to Hana

Back to Maui

Back to Hawaii

Through winding roads and picturesque sites, the 50 odd mile stretch between Paia and Hana showcases the diverse beauty of the Maui coastline and is an ode to the tropical rainforest the island hosts. While the western part of the island of Maui is arid and barren, the eastern part, dominated by the colossal Haleakala, receives a huge amount of rainfall being in the other side of a rain shadow. The stretch between Paia and Hana has some of the spectacular coast views, numerous waterfalls, challenging bends, narrow bridges, and to top it all, a misty rainforest. On the drive you will go in and out of the dry and wet zones and likely will encounter some random landslides and repair work.

Even though the drive is challenging, it is best to drive instead of taking a tour bus solely

hana2

Beauty and the Beast

because of the flexibility it offers. We trusted our tour guide app (see below) and the muscle of the rental roadster to push through the mists and fog in the rain forest, we stopped many times, even more than the stops our personal tour guide (check out the driving trip guide details) suggested. Travel sites dedicated to this scenic highway (e.g. Roadtohana) has a detailed list of places to stop, explore and take pictures along the way to Hana. Here are a few that cannot be missed:

  • Town of Paia – Take a stroll and have breakfast in this quaint little town. Fill up on gas and take restroom breaks here as these two are hard to come by in the upcoming stretch to Hana. After leaving the city of Paia, there is a Kuau store right before entering the main stretch of Hwy 36, to pick up coffee and sandwiches/snacks to-go.
  • Ho’okipa Lookout (Mile #9) – Along the road to Hana, you will see the coast a hundred times,
    hana8

    Ho’okipa Lookout

    but this is the best place to catch an expansive view with windsurfers and kitesurfers scoping the massive waves.

  • Kaumahina Park – Boasts a dramatic view of the northeastern coast with steep cliffs and the forest plunging in a hurry to kiss the surf.
  • Ke’anae Arboretum – There is a paid attraction called Garden of Eden at Mile #10, but we suggest you avoid that and instead spend some time in the Ke’anae Arboretum. Park anywhere hana6along the street and cross the road carefully to enter. There are no clear signs but the entrance is to the right side of the road (while traveling to Hana). Explore some of the Flora and Fauna of the rainforest here.
  • Halfway to Hana – Be sure to stop here at any of the stores and park carefully. Spend 15-20 minutes to taste the fresh baked banana bread and beverages. Probably the best banana bread in the islands, so don’t miss it. Oh, and fresh fruits too. Have some fresh pineapples and green coconut if you can find them.
  • Upper Waikani Falls and Hanawai Falls – Among all the waterfalls that can be seen hana1along the route in the side of a little bridge, these two are our favorites. Parking can be difficult, but be patient. Most people will not spend more than 15 minutes at these sites. Park safely and enjoy! The main waterfalls are in the right but don’t forget to look to the left since heavy rainfall sometimes makes the trailing edge of the waterfall more beautiful than the main one.
  • Nahiku Marketplace – Fun spot to pick up some gifts (but bargain first), and have a meal. Try the kahlua pork tacos.
  • Wai’anapanapa State Park (Mile #32) – Gorgeous views of the rocky cliffs, black sand
    waianapanapa-park-beach

    Black sand beach

    beach, freshwater caves and history await as you meander through the pebbly trail. Be sure to pack your swimsuit to take a dip in the ocean or at least to soak your feet here. Black sand beaches with low surf are not that easy to come by, afterall.

  • Hana – A quaint little sleepy town on the water, Hana, has probably not changed over the centuries. Home to historic battle sites, places of worship, and surrounded by legends, this town requires you to spend at least an hour to gather the pointers for your storyteller self.
  • Kipahulu (Mile #42) – It is a part of the Haleakala Nat’l park and you can reuse your ticket for 7 days. This portion of the park is in the rainshadow area and therefore does not get that much rain. Spend an hour or so in the trails to explore the seven sacred pools and the Waimoku falls.

 

Flora, Fauna and the Environment

  • Rainforest – Hawaiian islands have the only tropical rainforest in the US. The rainforest in Maui is created due to the enormous Haleakala volcano standing tall blocking the strong trade winds coming in with the moisture from the Pacific. The Haleakala National Park is itself divided into the rain shadow and the rainforest zones and visitors can explore both sides in their trip to the park. The eastern side is the rain shadow.

    Rainbow Eucalyptus

  • Rainbow Eucalyptus birch –  Commonly found in the rainforest along the way to Hana, this tree has multi-colored streaks on its trunk. It is native to Philipines and was introduced to Hawai’i in the 18th century. Due to the sturdiness and fast growth patterns, it was commonly used for construction purposes.

 

Essential Travel Tips

  • Food/Beverages – We were a little misguided by Tripadvisor stories on the lack of food options along the highway, and packed lunch from the Kuau store in Paia. Although you can pack some light snacks in Paia, there are a lot of local restaurants and a couple of marketplaces around the middle of the highway. The joints might not have a wide range of options, but trust us, the food and snacks are delectable.
  • Gas – Be sure to fill up the tank in Paia. There are no gas stations until you reach Hana.
  • Restrooms are available in the scenic spots, but are scanty. So prepare accordingly.

Hawaii Volcanoes National Park

Back to Hawaii

Back to Big Island

One of the UNESCO World Heritage Sites, covering over 500 sq. miles of land covered with rock formations and fresh lava flow, Hawaii Volcanoes National Park is a heaven for Geologists. The Mauna Loa and Kilauea volcanoes are the two shining stars in this park that is criss-crossed with trails and paved roads. After entering the park, follow an offline map, or use one of the Driving Tour Smartphone Apps (e.g. Shaka Guide).

For the list of places to cover, refer to Tripadvisor or any public sites including the NPS portal (Click here for a detailed offline printable map).

We thought sharing a little bit of knowledge about Volcanoes and the park might be helpful in your next visit to the park in relating to the concepts much easily. If you are interested in learning about Volcanoes and the formation of Earth, read on.

Hawaii Volcanoes: The history and science behind it

All the Hawaiian Islands and Emperor seamount chains are part of a mantle plume system. Mantle plumes or hotspots are nothing but molten rocks (lava) that rise from deep in the earth (mostly mantle) and reaches the surface of the earth through a weak zone (could be some deep fractures). The other common examples of islands created by hotspots are Iceland, Galapagos, etc.

Mantle plumes are stationary and can erupt through hundreds of years to millions of years before going extinct. Hawaiian plume has been erupting for millions of years creating Emperor Seamount chains, followed by Kauai which is the oldest island in Hawaii. As the Pacific plate moved over the plume, it went on to create Oahu, Maui, and the rest of the Hawaiian Islands before creating the Big Island. The hotspot is under Big Island currently. As the rate of plate motion has slowed down over the years, the same part of the plate is over the hotspot for a longer period, creating the largest island in Hawaii.

There are three types of lava flow structures that are most abundant in volcanic islands like Hawaii.

  • Pillow lavas: Pillow lavas are volumetrically the most abundant type commonly found in the underwater seamounts.
  • Pahoehoe lava: If lava cools slowly and does not move too fast it forms smooth ropy lava called pahoehoe. This type of flow forms some of the common features on the surface. Pahoehoe lava is characterized by a smooth, billowy, or ropy surface.Pahoehoe flows tend to be relatively thin, from a few inches to a few feet thick.
  • A’a lava:If lava cools quickly and moves fast it can tear into pieces called A’a.  A’a flow is characterized by a rough, jagged, spinose, and generally crackly surface. A’a lava flows tend to be relatively thick compared to pahoehoe flows. A’a flows, while rocky and sharp on the top, are extremely dense underneath – producing some of the most difficult rocks to cut through. Several hikes in the National Park take you past huge boulders of dense solid A’a. It is easy to compare with Pahoehoe that tends to be in layers.

Pele’s hair and Pele’s tear: Named after the Hawaiian goddess of fire, Pele, these structures form during times of high fire-fountaining. Pele’s hair are thin filaments of stretched out basaltic glass. Pele’s tears or Achneliths are tiny droplets of lava that look like tear-drops.

Sulphur Springs abundant with Pele’s hair and tears

Researchers have found that these are formed by the same overall process from the lava fountains, depending on the velocity of the erupting lava. High velocity and strong winds favor formation of Pele’s hair. Sometimes Pele’s tears are found attached at the tips of Pele’s hairs.

Big island has multiple volcanoes both active and dormant. Three major ones are –

  1. Mauna Kea – Dormant Cinder Top Volcano, 4,205m tall. Has a steep and irregular topography compared to other similar volcanoes in the area.
  2. Mauna Loa – Another cinder top volcano at 4,170m tall, it is younger than Mauna Kea, and erupts every few years.  A series of earthquakes beneath Mauna Kea may signal that an eruption could occur within a short time, although it cannot predict the magnitude of eruption.
  3. Kilauea – In the last few years, Kilauea volcano is active and erupting continuously. Before going to Hawaii, do check the current lava flow status here. The recent eruptions are from the Halema’uma’u Crater at its summit and from the Puʻu ʻŌʻō vent in towards the east. Lava flow from Puʻu ʻŌʻō is relatively recent (30 years old) and continues to enter the ocean at Kamokuna. Although surface flows have been common in this eruption, most of the lava from the vent travels concealed in lava

    tubes until it reaches the ocean. A blowout during a 2008 eruption built a lava lake in Halema’uma’u crater, which is a remnant of a past explosion. The lava is in this crater is as light as water. The base level of the crater is unstable to the point that it rises and falls by the minute. The gaping hole through which the eruption is visible, is a direct conduit into Kilauea’s magma reserves. This crater is just a gentle reminder how active and dynamic our mother Earth really is.

The experience of witnessing rock in its bright molten state and watching new land being formed is quite a fascinating experience, if you are lucky enough to witness it. When hot lava enters the water, it bursts into pieces, building new land at the ocean edge from the fragmental material. This pile of rubble is then covered with a veneer of lava flows, forming a “bench”. Initially the bench is weak enough that it can collapse with the smallest disturbance around it. After multiple layers of such deposits and cooling of magma, typically taking several hundred years, once the bench is stable and large enough, a new island is created. After hundreds of years of depositions of lava followed by some tectonic activity (earthquake mostly) those submerged islands rose above the water and resulted in the islands the way we see them in the present. In a nutshell, that is a brief history of the Hawaiian Islands. There are multiple islands like these that are currently submerged under the ocean in the area, and in a few hundred years we will be able to see another island full of volcanic activity, south of the Big Island.

Tips Before Visiting the Park

Although there are clearly marked barriers and signs at sites, there are some common sense warnings that one MUST follow. Read on to find out the science and geology behind those hazards and why it is important to follow them for your own safety.

  • What are the Volcanic Hazards Facing you?
    • Bench collapse can cause a 100-200 feet steep drop into unknown craters
    • Rock jets & littoral fountains hurl hot lava that erratically gets sprayed
    • Steam blasts toss rocks
    • Acid fumes (Sulphur di oxide, carbon monoxide) and glass particles can irritate eyes and lungs causing suffocation and choking
    • Scalding waves burn where lava meets ocean
  • Recommendations:
    • Do not stand near the steep cliffs. This land is extremely weak and breaks off frequently; it is impossible to climb up from the crater or ocean vertically.
    • Do not go on the rocks close to a volcanic eruption. Bench collapses have killed people.
    • Do not go near the water as it can be boiling hot and likely contains sulphur fumes.
    • Move inland quickly if you hear unusual noises.
    • Please be prepared for personal hazards especially when hiking through the enormous lava fields:
      • Most injuries are not directly due to the eruption. Intense sunlight and high temperatures can lead to dehydration, heat exhaustion, or sunstroke. Air temperatures near lava flows can exceed 120°F (49°C), depending on cloud cover and wind conditions.
      • At higher elevations, wind and rain can lead to hypothermia (low body temperature). Carry sunscreen and a hat, and drink more water than you think you need.
      • Injuries from a fall are common. It is easy to break through a thin, overhanging crust of lava or trip on a crack and fall on the abrasive, glassy surface. U.S. Geological Survey (USGS) scientists always wear long pants, sturdy boots, and sometimes gloves when working near the flows. Never shorts and flip-flops!
      • Before visiting the lava field, check with Park Rangers for current conditions and for the best approach route. Park Rangers do not recommend that you attempt the hike to the coast if you are unprepared or uninformed. The area is remote, has no shade or water source, and is seldom patrolled. Also, most areas in the park has no cellphone reception.

If you are interested to find out more about Hawaiian Volcanoes there are plethora of information in the internet. Some of the sites that I personally like are:

  • USGS website in general. Their live webcam of Kilauea is quite fascinating.
  • Universities often organize field trips to the Hawaiian Volcanoes and their reports are usually easy to follow and contains lots of authentic interesting information. One of such link is here

Because of their altitude, the summits are covered in snow in winter and are usually cold and windy in the rest of the year. So, if you plan to go for star gazing, sunset viewing at the summit, or hiking up to the visitors’ center (beyond which tourists are not allowed to drive on their own) please be prepared with warm clothes unless you are used to the Polar weather!! If you go for star gazing and sunset viewing (highly recommended) with a tour company (read our experience), they usually provide parkas. However, if you are like me to whom anything below 55˚F (10˚C) is freezing please carry a pair of gloves, and wear long pants (preferably wind buster), and close toed comfort shoes are also highly recommended.

Mauna Kea Summit

Back to Hawaii

Back to Big Island

Mauna Kea is a dormant volcano in the center of the Big Island, and is about 14000 feet high. Due to the easy access to the summit, taking about 2 hours from sea level, several observatories are set up at the top. It also attracts scientists and astronomy enthusiasts from around the world.

But before venturing into the wild, precautions are necessary to drive up to the summit –

  1. Altitude sickness can sneak in any time because of quickly changing altitude and thinning oxygen content of the air.
  2. Only 4 wheel drive cars are allowed to travel beyond the Visitor Center (at 9000 feet).
  3. It can be extremely cold with heavy winds. So layers are important. Also staying hydrated and warm are key to enjoy the surreal beauty of the night sky.

We took the Mauna Kea summit adventures tour with stargazing (cost ~$450 for two). Although we hate conduced tours, especially the ones that deal with science and nature. With slightly above average knowledge about the geology and science of volcanoes, this tour seemed a little below par in providing intriguing information.

We were picked up from the Kailua-Kona market area around 2:45PM. The pickup spot was conveniently located, and the driver was on time. We took the longer route to reach the park visitor center to pick up other guests. En route, the driver did give out some information that was interesting but being jetlagged, we got into intermittent slumbers (so it was not that interesting after all. ;-)).

Once up to the top visitor center, we were given out Parkas and gloves. For the ones who bought the dinner, warm lasagna was served here as well in aluminum foils. We did not get the dinner option and instead carried sandwiches (which I’d strongly recommend since we heard the food was not palatable enough).

It gets really windy and starts getting low on oxygen. So it is normal to feel dizzy, and the best way to beat that is the breath slowly and walk/eat at a moderate pace. Staying warm is also important so take opportunity to grab coffee, hot chocolate or tea.

After spending ~45 minutes here, we hopped on to the bus and headed to the peak. The drive up was slow and adventurous. Once up there, just before the sunset, it got dark

quickly, wind picked up, and the cold was borderline unbearable. But having set up the tripod in time, I was able to grab some stunning sunset pictures.

Due the altitude, it was not advisable to stay up there for long. Therefore we headed down in the dark and could slowly see the stars above shining bright. We stopped near the visitor center and parked somewhere empty so that other cars’ headlights don’t spoil the mood.

There was a large telescope setup in the visitor center and there was a long queue for stargazing. Our private tour had two telescopes set up and we could take turns in seeing the Milkyway, Venus, Saturn, Proxima-Century and a supernova. The guides were patient enough to explain what we were seeing. There was hot chocolate/coffee and snacks as well for everyone to stay warm.

We started our descent around 9pm when the stars of interest started going below horizon. After an exhausting day of excursions, we were back to the hotel and ready to hit the couches by midnight.

In conclusion, we do want to state that it is one of the very few places in the world where regular visitors can climb that kind of an altitude, driving. The amount of stars you can see in the darkest of the nights is surreal. Walking in the summit would make you wonder if you are still on Earth or suddenly teleported to Mars or the Moon. Definitely a MUST do in Big Island.
